- Air Consumption: Efficient operation minimizes operating costs.
Material Composition
Standard industrial materials: aluminum housing, stainless steel internals, and synthetic elastomer seals. Compatible with clean, dry instrument air.
Structural Characteristics
Compact, rugged design with standard mounting dimensions. Features external adjustments and a local pressure gauge. The “-00” designation may be marked on the nameplate or in the ordering code.
Working Principle
Standard force-balance pneumatic positioning. The input signal is compared to valve position, and the relay adjusts actuator pressure to eliminate any error.
Installation Requirements
Standard installation procedures apply. Mount securely, connect air and signal lines, and adjust the feedback linkage for proper travel.
Usage Precautions
- Ensure air supply is filtered and regulated.
- Check for air leaks regularly.
- Calibrate zero and span after installation or maintenance.
